Write the balanced chemical equations for the following reactions-

(a) Sodium carbonate on reaction with hydrochloric acid in equal molar concentration gives sodium chloride and sodium hydrogen carbonate.

(b) Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide.

(c) Copper sulphate on treatment with potassium iodide precipitates cuprous iodide $({Cu}_{2} I_{2})$ , liberates iodine gas and also forms potassium sulphate.

Write the balanced chemical equations for the following reactions:
Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide.

The correct option is D $N a H C O_{3} + H C l \to N a C l + H_{2} O + C O_{2}$
$N a H C O_{3} + H C l ⟶ N a C l + H_{2} O + C O_{2}$
